Included Skills1

spindleskills/spindle/SKILL.md

Operate Spindle's evidence-bearing lifecycle for agent skills. Use to inspect, discover, try, borrow, adopt, update, distill, disable, roll back, or retire a skill; explain active skill state; or diagnose startup, conflict, version, and harness state. Do not trigger for ordinary work that merely uses an active skill.
